Description

Technical Field

[0001] This utility model belongs to the technical field of mine detection, specifically relating to an integrated device for mine drilling inspection, limiting, cleaning and scraping. Background Technology

[0002] In many cases, due to the relatively soft rock or coal at the borehole, small pieces of gravel and mud fall into the borehole and block the lens of the probe, so that the testing work needs to be repeated, reducing work efficiency. At the same time, ordinary borehole inspection instruments only serve to take pictures of the borehole wall and cannot obtain information on indicators such as rock hardness or strength. Furthermore, during the pushing process, there is a problem that the detection device is difficult to keep in the center position.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides an integrated device for drilling, viewing, limiting, cleaning and scraping in mines.

[0006] A mining borehole inspection, limiting, cleaning, and scraping integrated device includes:

[0007] An adjustable limiter is a columnar hollow structure made of elastic material, which is fitted onto the threaded part of the outer wall of the guide head. At both ends of the adjustable limiter, there are screw rings corresponding to the threaded part of the guide head, so that the adjustable limiter can be squeezed by adjusting the distance between the two screw rings, so that the adjustable limiter can deform radially and adapt to the drilling.

[0008] A steel wire rope, which is connected to the guide head, is used to pull the adjustable limiter to move within the borehole;

[0009] A viewing probe, which is disposed at the front end of the guide head, is used to acquire images inside the borehole;

[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art are within the protection scope of this utility model.

They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected" and "linked" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0030] like Figure 1-4 As shown, a mining drilling inspection, limiting, cleaning, and scraping integrated device includes an adjustable limiter, a steel wire rope 4, an inspection probe 11, a water pipe 5, and a sensor 3. The adjustable limiter is a columnar hollow structure made of elastic material, which can deform radially under axial compression, thereby changing its diameter. It can be adjusted to adapt to drill holes of different diameters. The guide head 1 is a columnar structure with a threaded part on its outer wall in the middle. The adjustable limiter is sleeved on the threaded part of the outer wall of the guide head 1. There are screw rings 10 at both ends of the adjustable limiter. The inner wall of the screw rings 10 has internal threads corresponding to the threaded part, so it can be connected to the threaded part of the guide head 1 by threaded assembly. By turning the two screw rings 10, the distance between the two screw rings 10 can be adjusted. Under the compression of the screw rings 10, pressure can be applied to the adjustable limiter in the axial direction, thereby causing the adjustable limiter to open to the adapted drill hole after radial deformation.

[0031] In this embodiment, the adjustable limiter is moved within the borehole by the traction of the steel wire rope 4. The steel wire rope 4 is connected to the rear end of the guide head 1. A viewing probe 11 is set at the front end of the guide head 1. The viewing probe 11 is a miniature camera that can collect images inside the borehole as the guide head 1 moves.

[0032] In addition, the guide head 1 has a gap, and a water pipe 5 is installed inside it. One end of the water pipe 5 is connected to the water pump 8, and the other end extends to the side of the inspection probe 11 to clean the inner wall of the borehole and the inspection probe 11. A sensor 3 is also installed on the side of the guide head 1 to detect the inner wall of the borehole as it moves with the adjustable limiter.

[0033] The sensor 3 can be of various types, such as a hardness tester, an acoustic sensor 3, or a vibration sensor 3. The acoustic sensor 3 collects the sound generated when the probe scrapes the inner wall of the borehole, and measures the hardness of the borehole wall by the sound frequency and sound level. The vibration sensor 3 collects the vibration magnitude when the probe scrapes the inner wall of the borehole, and measures the hardness of the borehole wall by the vibration amplitude. The hardness tester is located at the end of the probe and can directly measure the hardness of the borehole wall. The viewing probe 11 is connected to the controller 9 and the display via a data cable.

[0034] In this embodiment, the three sensors collect data. The analysis of the hardness of the borehole inner wall is obtained by data calculation and processing using specific software. The software can be a computer, mobile phone, etc., and there are no restrictions on the software or the carrier.

[0035] A fixed frame 6 is provided at the borehole opening. The fixed frame 6 is equipped with a fixed pulley corresponding to the steel wire rope 4 and a cable counter 7. The cable counter 7 records the meter length by rotating the pulley when the guide head 1 enters or exits the borehole, as the steel wire rope 4 is wound around it. The sensor 3, the cable counter 7, and the display are connected to a controller 9, which can be a computer host.

[0036] When using, adjust the adjustable limiter to fit the drill hole, send the guide head 1 to the hole opening, connect the guide head 1 to the water pipe 5, steel wire rope 4, sensor 3 data cable and viewing probe 11 data cable, connect the water pipe 5 to the water pump 8, and check the working status of the water pump 8; connect the controller 9 to the display, wind the steel wire rope 4 onto the pulley, rotate the meter counter to check if the meter counting is normal, touch or lightly tap the sensor 3 to check if the sensor 3 data is normal.

[0037] After the controller 9 resets the meter reading of the cable counter 7 and the data of the sensor 3 to zero, recording begins. During operation, the hollow steel pipe pushes the rear end of the guide head 1 and slowly pushes it into the borehole at a uniform speed. When small gravel or mud-like material adheres to the viewing probe 11, it can be cleaned through the water pipe 5.

[0038] The guide head 1 is equipped with a lamp corresponding to the viewing probe 11. A nozzle 12, connected to the water pipe 5, is located at the front end of the guide head 1. The nozzle 12 points towards the viewing probe 11 and the lamp, effectively removing debris and mud from the lens and lighting device of the viewing probe 11 in real time, thus avoiding the repeated testing problems caused by lens contamination in traditional methods. Combined with the adjustable limiter 2, it ensures the probe remains centered in the borehole, reducing image distortion and significantly improving the clarity and stability of the borehole wall imaging, thereby increasing detection efficiency.

[0039] In an optional embodiment, in order to adapt the sensor 3 to drill holes of different diameters, a corresponding spring 13 extending radially is provided on the outer wall of the guide head 1, and the rear end of the sensor 3 is connected to the spring 13. This ensures that the sensor 3 can fit tightly against the hole wall during use, and can be deformed to make way when passing through the concave and convex positions inside the drill hole. The sensor 3 can also be repositioned by the deformation of the spring 13 when being pushed in and out.

[0040] The guide head 1 has frustum-shaped, cone-shaped, or hemispherical guide portions at both ends, which facilitates movement within the borehole.

[0041] In an optional embodiment, the adjustable limiter comprises a ring 201 and elastic strips 202, wherein the elastic strips 202 are either steel or rubber strips, and the ring 201 can be a metal ring adapted to the screwing ring 10, with the inner diameter of the ring 201 matching the outer diameter of the guide head 1. Multiple elastic strips 202 are evenly distributed between two rings 201 and are circumferentially distributed about the rings 201. When the screwing ring 10 applies pressure to the two rings 201, the elastic strips 202 are compressed and pushed outward to form a lantern-shaped structure, thus adapting to the borehole diameter. This allows for flexible adjustment based on the borehole diameter, preventing probe misalignment or jamming, and reducing the risk of falling.

[0042] Sensor 3 is flexible, detachable, and replaceable. It can dynamically collect data on the hardness, vibration, or acoustic properties of the borehole wall and generate borehole columnar graphs and mechanical performance curves in real time on the display. This function makes up for the limitation of traditional viewing instruments that can only acquire image information.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
